One end of the plurality of hydraulic lines 28 are connected to the plurality of joysticks 24 and the plurality of hydraulic treadles 26.

A hydraulic pressure line 102 and a hydraulic return line 104 of a hydraulic pump 100 are connected to an input of a hydraulic circuit block 36. The hydraulic pump 100 distributes hydraulic fluid to the plurality of hydraulic joysticks 24 and hydraulic treadles 26 through the hydraulic circuit block 36. The plurality of quick disconnect adapters 36 are threadably engaged with the plate member 32 on one side thereof. The plurality of threaded adapters 38 are threadably engaged with the plurality of quick disconnect adapters 36 on an opposing side of the plate member 32. A plurality of hydraulic pressure sensors 34 are threaded into the plurality of threaded adapters 38. Hydraulic pressure in the joysticks 24 and foot treadles 26 hydraulic lines 28 are measured by the plurality of hydraulic pressure sensors 34. An electrical output from each hydraulic pressure sensor 34 is connected to the cab bridge controller 20. The electrical bulkhead 18 includes a signal socket 42 and a power socket 44. A signal cable 46 includes a bulkhead plug 48 extending from one end and a controller plug 50 extending from an opposing end. The bulkhead plug 48 is plugged into the signal socket 42 and the controller plug 50 is plugged into the cab bridge controller 20 for transfer of electrical signals from the cab member 10 to the cab bridge controller 20. A vehicle controller 45 is preferably used to receive electrical signals from a button panel 47. The vehicle controller 45 is also used to display information to an operator display 49. The operator display 49 also includes a touch screen. The touch screen may be used to send electrical signals from the operator display 49. The vehicle controller 45 is also connected to the cab bridge controller 20 through electrical bulkhead 18.

An output from the cab bridge controller 20 is connected to the cab transceiver 22. The cab bridge controller 20 converts the electrical signals from the plurality of hydraulic sensors 34 and the vehicle controller 45 into a suitable form for wireless transmission. The cab transceiver 22 transmits the plurality of electrical signals from the plurality of hydraulic pressure sensors 34 and electrical signals from the signal socket 42 to a frame transceiver 52.

A power cable 54 includes a generator plug 56 on one end and a power plug 58 on an opposing end. The generator plug 58 is plugged into an electrical generator 106 and the power plug 56 is plugged into the power socket 44.

The hydraulic pump 100 and the electrical generator 106 may be connected to the remote wireless hydraulic cab 1 from any other suitable source, besides the docking station 12. The hydraulic sensor plate 16, the cab bridge controller 20 and the cab transceiver 22 would be physically retained on the remote wireless hydraulic cab 1 and not on the docking device 12.

A diagnostic device 66 may be connected to the cab bridge controller 20 through a wired connection to monitor hydraulic pressures of the joysticks 24 and foot treadles 26, and status of the buttons of the button panel 47. A diagnostic device 68 may be connected to the cab bridge controller 20 through a wireless connection.

With reference to FIGS. 8-10 , the electro-hydraulic conversion valve 55 preferably includes a valve block 90, a plurality of proportioning valves 92, at least two shuttle valves 94 and a frame pilot hydraulic circuit 96. The valve block 90 includes a plurality of proportioning threaded taps for receiving the plurality of proportioning valves 92; a high side inlet for receiving pressurized hydraulic fluid for the plurality of proportioning valves 92 from the frame pilot hydraulic circuit 96; a return outlet for returning hydraulic fluid from the plurality of proportioning valves 92 to a tank 98 and a plurality of supply outlets for supplying various hydraulic components with pressurized hydraulic fluid. The shuttle valves 94 send an electrical signal to an alarm device, when the remote wireless hydraulic frame 2 is moving.

A supply passage 108 is formed in the valve block 90 to supply the plurality of proportioning valves 92 with hydraulic fluid from the frame pilot circuit 96. A return passage 110 is formed in the valve block 90 to receive hydraulic fluid from the plurality of proportioning valves 92. A supply outlet 112 of each proportioning valve 92 supplies hydraulic pressurized hydraulic to a particular hydraulicly operated component 114 preferably through a hydraulic bulkhead 116. An output pressure of each proportion valve 92 is determined by a hydraulic electrical signal sent from the frame bridge controller 53. The hydraulic electrical signal originates at a hydraulic control device, such as the hydraulic joystick 24 or the hydraulic foot treadle 26. A control electrical signal originates from an electrical control panel 47 or an operator display 49. The electrical control panel 47 includes a plurality of buttons and knobs. The operator display 49 includes a touch screen. The joystick, foot treadle, electrical control panel and touch screen are located in the hydraulic remote cab 1. A hydraulic pressure transmitted from the joystick 24 or foot treadle 26 is converted into the hydraulic electrical signal by the hydraulic pressure sensor 34. The hydraulic electrical signals and control electrical signals are sent to the cab bridge controller 20. The plurality of hydraulic electrical signals and control electrical signals are converted into a suitable protocol by the cab bridge controller 20 and sent to the cab transceiver 22. The cab transceiver 22 wirelessly transmits the hydraulic and control electrical signals to the frame transceiver 52.

The frame bridge controller 53 receives the hydraulic and control electrical signals from the frame transceiver 52 and converts the signals into a suitable form. The hydraulic and control electrical signals are sent from the frame bridge controller 53 to the electro-hydraulic conversion valve 55, a hydraulic controller, an engine controller and the at least one electrical component 86. The hydraulic electrical signals sent to the electro-hydraulic conversion valve 55 operate the plurality of proportioning valves 92 to control the flow of hydraulic fluid to various hydraulicly operated components 114. However, a remote wireless electrical cab could be used with the remote hydraulic frame. The remote wireless electrical cab would have electrical joysticks and foot treadles, instead of hydraulic joysticks and foot treadles. The hydraulic controller 118 would be used to operate the hydraulic operated components 114 and the at least one tool 88 instead of the electro-hydraulic conversion valve 55. Outlet hydraulic lines 112 from the electro-hydraulic conversion valve 55 preferably include quick coupling ends for retention in a plurality of hydraulic connectors in the hydraulic bulkhead 116. The hydraulic electrical signals are also sent to the hydraulic controller 118. The control electrical signals go to the engine controller or the at least one electrical component 86.

A diagnostic device 122 may be connected to the frame bridge controller 53 through a wired connection to monitor various hydraulic pressures of the frame operated components 114 and status of the hydraulic controller 118, the engine controller 120, and electrical components 86.
